Polymer Filament Polymer filament is the raw material used in FDM 3D printing, made from thermoplastics such as PLA, ABS, PETG, Nylon, and Polycarbonate. It is extruded into thin strands, typically 1.75 mm or 2.85 mm in diameter. Polymer filaments vary in mechanical properties, temperature resistance, and flexibility. They are available in various colors, finishes, and composites, including carbon fiber, metal, and wood-filled variants. Proper filament storage prevents moisture absorption and degradation. Selecting the right polymer filament ensures optimal print quality and functionality. |
